SRAM Quarq ELSA 10R Power Meter 53/39T BB30 Crankset

Weighing in at 44g lighter than the Quarq CinQo, the SRAM Quarq ELSA 10R BB30 Power Meter comes with new technologies to elevate your power and performance. Power Balance feature lets you measure watts separately for each leg, and OmniCal feature lets you swap chainrings without needing to recalibrate. SRAM Red Exogram Hollow Carbon crankarms are lighter, stronger and stiffer than ever. CNC machined aluminum spider houses several integrated electronics: a replaceable CR2032 battery lasting up to 300 hours, an LED indicator that blinks when the unit is powered-up or calibrated, and a visible ANT+ ID to aid pairing. The SRAM Quarq ELSA 10R BB30 Power Meter takes your ride to the next level.
